DETAILED DESCRIPTION

[0028] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0032] See also Figures 1 to 3 The splitting knife storage and retrieval machine to be protected by the present invention comprises a housing 1 and a silo 2, a feeding mechanism 3 and a transfer mechanism 4 arranged inside the housing 1. The housing 1 is provided with a discharge port 13, the silo 2 comprises a plurality of storage bins 231 for longitudinally accommodating splitting knife boxes 101, and the feeding mechanism 3 comprises a feeding assembly 31, a visual recognition assembly 32, a direction-changing assembly 33, a pushing assembly and a rotating gripper 35. The feeding assembly 31 sequentially transmits a plurality of horizontally arranged splitting knife boxes 101 to the direction-changing assembly 33, the direction-changing assembly 33 controllably adjusts the setting direction of the splitting knife boxes 101, the visual recognition assembly 32 identifies the setting direction of the splitting knife boxes 101 located at the direction-changing assembly 33, and identifies and records the label information of the splitting knife boxes 101 when the setting direction of the splitting knife boxes 101 is the target direction. The pushing assembly pushes the splitting knife box 101, so that the rotating gripper 35 grabs the splitting knife box 101 and rotates it, and at this time, the splitting knife box 101 is arranged in the first position along the longitudinal direction. The transfer mechanism 4 transfers the chopping knife box 101 arranged in the longitudinal direction between the discharge port 13 , the first position and any material storage bin 231 .

[0033] The multiple stacked splitting knife boxes 101 are transferred to the direction-changing component 33 in sequence through the feeding component 31, and the direction of each splitting knife box 101 is unified through the direction-changing component 33. After the visual recognition component 32 recognizes the label information and completes the information entry, the direction of the splitting knife box 101 is converted to a longitudinal direction for easy storage through the pushing component and the rotating gripper 35, so that the transfer mechanism 4 can store the multiple splitting knife boxes 101 in the storage bin 231 of the silo 2 in sequence. By transmitting multiple splitting knife boxes 101 in sequence and changing the direction to identify the label information, the need for one-time loading of a large number of splitting knife boxes 101 is met, and the practicality of the splitting knife storage and retrieval machine is improved. The splitting knife box 101 is easy to operate when loaded horizontally, and it is not easy to fall off when stored vertically and has a high capacity, which also helps to improve the practicality of the splitting knife storage and retrieval machine.

[0034] In some embodiments, the direction changing assembly 33 includes a roller frame 331, a first roller 332 and a second roller 333. The first roller 332 and the second roller 333 are both rotatably connected to the roller frame 331 and are both parallel to the transversely arranged cleaving box 101. The first roller 332 and the second roller 333 are both controllably rotatable along the central axis. The cleaving box 101 is supported between the first roller 332 and the second roller 333 and controllably rotates under the drive of the first roller 332 and the second roller 333. The roller frame 331 is controllably rotatable in a plane parallel to the first roller 332 and the second roller 333. The orientation of the cover 102 of the cleaver box 101 is adjusted by rotating the roller frame 331. There is no need to put the cleaver box 101 into the feeding assembly 31 in the same orientation. The cleaver box 101 is driven to roll by the first roller 332 and the second roller 333, so that the label information on the side wall of the cleaver box 101 is exposed to the recognition range of the visual recognition assembly 32, which is convenient for collecting and recording the information of the cleaver unit, thereby improving the practicality of the cleaver storage and retrieval machine.

[0035] In some embodiments, the splitting knife storage and retrieval machine further includes a material return mechanism 5, and a material return port 14 is provided on the housing 1. The material return mechanism 5 is used to transfer the splitting knife box 101 entering the material return port 14 to the redirection assembly 33. By providing the material return mechanism 5, it is helpful to realize the control of scrapped splitting knives, improve the control strength, and reduce the risk of economic losses caused by the loss of the splitting knife box 101. The material return mechanism 5 is connected with the redirection assembly 33, and the common splitting knife storage and the scrapped splitting knife return share a set of information identification and input and transfer to the silo 2 structure, which helps to simplify the structure and reduce space cost and construction cost.

[0036] In some embodiments, the material return mechanism 5 includes a material return conveyor belt and a material return sensor 53. The material return conveyor belt is used to transfer the splitting knife box 101 entering the material return port 14, and the material return sensor 53 is used to sense the splitting knife box 101 reaching the sensing position on the material return conveyor belt. By providing the material return sensor 53, the feeding component 31 is suspended during the material return process, reducing the risk of mixing ordinary splitting knives with scrapped splitting knives.

[0037] In some embodiments, the material return mechanism 5 includes a barcode scanner 151 disposed on the outer wall of the housing 1, and the barcode scanner 151 is used to identify the label information of the cleaver box 101 to be returned. Accurately entering the label information of the scrapped cleaver to be returned by the barcode scanner 151 helps reduce the risk of confusing ordinary cleavers with scrapped cleavers.

[0038] In some embodiments, the transfer mechanism 4 includes a first manipulator 41, a plurality of transfer components 42, and a second manipulator 43. The transfer component 42 is used to carry the splitting knife box 101 and reciprocate between the second position and the third position. When the splitting knife box 101 is put into storage, the first manipulator 41 transfers the splitting knife box 101 set at the first position to the second position along a preset direction, and the second manipulator 43 transfers the splitting knife box 101 set at the third position to any storage bin 231. When the splitting knife box 101 is taken out of storage, the second manipulator 43 transfers the splitting knife box 101 set at any storage bin 231 to the third position, and the first manipulator 41 transfers the splitting knife box 101 set at the second position to the discharge port 13. By splitting the transfer process into three processes and carrying them out by the first manipulator 41, the transfer component 42, and the second manipulator 43 respectively, the transfer distance and time required by the first manipulator 41, the transfer component 42, and the second manipulator 43 are reduced, and the transfer efficiency is improved.

[0039] In some embodiments, the shell 1 also includes an NG port 12. When the visual recognition component 32 fails to recognize the label information of the splitting knife box 101 located at the change-direction component 33, the first robot 41 transfers the splitting knife box 101 from the first position to the NG port 12, thereby improving the system fault tolerance.

[0040] In some embodiments, the feeding assembly 31 includes a feeding conveyor belt 311 and a feeding trough 312. The feeding trough 312 includes a longitudinally arranged resistance surface (not shown), an inclined guide surface 3121, and a plurality of lifting platforms 3122 arranged between the resistance surface and the guide surface 3121. The height of the side of the guide surface 3121 close to the resistance surface is relatively low. The lifting platform 3122 is configured in a long strip shape and has an inclined lifting surface 3123. The chopping knife box 101 slides from the guide surface 3121 of the feeding trough 312 to the lifting platform 3122. The lifting surface 3123 and the lifting platform 3122 are controllably raised and lowered to transfer the cleaver box 101 to the top of the resistance surface of the feeding trough 312, so that the cleaver box 101 slides to the feeding conveyor belt 311 in turn, and the feeding conveyor belt 311 extends toward the changing component 33. The lifting platform 3122 lifts and transfers the multiple cleaver boxes 101 stacked in the feeding trough 312 to the feeding conveyor belt 311 in turn, thereby entering and transferring the information of each cleaver in turn, which helps to realize the separate storage and use of the cleavers, thereby realizing the information management of the cleavers.

[0041] In some embodiments, the feeding assembly 31 also includes a height limiting plate 313, which is arranged in the middle of the feeding conveyor belt 311, and the channel surrounded by the height limiting plate 313 and the feeding conveyor belt 311 can allow less than two splitting knife boxes 101 to pass through at the same time, further ensuring that the splitting arrives at the changing direction assembly 33 in sequence.

[0042] In some embodiments, the silo 2 includes a first motor 21, a rotating central axis 22 and a plurality of discharge discs 23. The plurality of horizontally arranged discharge discs 23 have different heights and are coaxially arranged. The rotating central axis 22 passes through and is connected to the center of the plurality of discharge discs 23. It is vertically arranged and controllably rotated under the drive of the first motor 21. A plurality of storage bins 231 are arranged on any discharge disc 23. The plurality of controllably rotatable discharge discs 23 help to store more chopping knife boxes 101 in a smaller space. By rotating the discharge disc 23, the positions of the chopping knife boxes 101 stored on the discharge disc 23 are close, thereby reducing the distance and range of the manipulator's transfer, improving the warehousing efficiency, reducing the performance requirements of the manipulator, helping to improve the efficiency of the chopping knife storage and retrieval machine, and reducing its construction cost.

[0043] Please refer to the following examples for details.

[0044] Embodiment 1:

[0045] See also Figure 1 and Figure 2 The splitter storage and retrieval machine shown in a preferred embodiment of the present application includes a hopper 2, a feeding mechanism 3 and a transfer mechanism 4, and a shell 1 wrapped around the outside of the above-mentioned structures. The shell 1 is provided with a feeding port 11, an NG port 12, a discharging port 13 and a return port 14.

[0046] The silo 2 includes a first motor 21, a rotating central axis 22 and a plurality of discharge discs 23 of the same structure. The rotating central axis 22 is arranged vertically, and the first motor 21 adopts a stepping motor, which drives the rotating central axis 22 to rotate controllably through a synchronous wheel set including a synchronous belt and a pair of synchronous wheels. A plurality of discharge discs 23 are horizontally connected to the rotating central axis 22 at different heights, and all rotate synchronously along the center of the circle driven by the rotating central axis 22. A plurality of groups of storage bins 231 are arranged on each discharge disc 23, and the storage bins 231 are configured in a circular through hole shape. The cleavers are stored in the cleaver box 101 in the same direction, and a cover 102 is arranged at one end of the cleaver box 101. The cleaver box 101 enters the storage bin 231 vertically from above the discharge disc 23 with the cover 102 in the upper direction, and is supported above the storage bin 231. The material storage bins 231 of the same group are arranged along the radial direction of the material discharging disc 23 and are equidistantly disposed, and the angles between two adjacent groups of material storage bins 231 are the same.

[0047] See also Figure 2 and Figure 3The feeding mechanism 3 includes a feeding component 31, a visual recognition component 32, a direction-changing component 33, a pushing component and a rotating gripper 35. The feeding component 31 sequentially transmits a plurality of horizontally arranged chopping knife boxes 101 to the direction-changing component 33. The direction-changing component 33 controllably drives the chopping knife boxes 101 to rotate along their axes until the label information on the side wall of the chopping knife boxes 101 faces the visual recognition component 32 and is recognized and recorded by the visual recognition component 32. The visual recognition component 32 recognizes and senses the setting direction of the chopping knife boxes 101 located in the direction-changing component 33. When the cover of the chopping knife boxes 101 faces a different direction from the target direction, the direction-changing component 33 drives the chopping knife boxes 101 thereon to rotate until the setting direction of the chopping knife boxes 101 is the target direction. At this time, the pushing assembly pushes the cover 102 of the cleaver box 101, so that the rotating gripper 35 grabs the end of the cleaver box 101 away from the cover 102, and the rotating gripper 35 drives the cleaver box 101 to rotate, so that the cleaver box 101 is set in the first position in the vertical direction with the cover 102 on top.

[0048] See also Figures 1 to 3 The feeding assembly 31 includes a feeding conveyor belt 311, a feeding trough 312, a height limiting plate 313, a return chute 314 and a first slide plate 315. The feeding trough 312 is configured as a box-shaped structure with an open top, and a feed inlet 11 is provided on the housing 1. The feed inlet 11 is a through hole connecting the inside and outside of the housing 1, and the position of the feed inlet 11 corresponds to the opening of the feeding trough 312. A plurality of chopping knife boxes 101 enter the housing 1 from the feed inlet 11 and are accumulated in the feeding trough 312.

[0049] The feeding trough 312 includes a contact surface, a guide surface 3121 and a lifting platform 3122. The inner wall of one side of the feeding trough 312 is a contact surface, and the contact surface is arranged in the vertical direction. The guide surface 3121 of the feeding trough 312 is inclined, and the height of one end of the guide surface 3121 close to the contact surface is lower. A plurality of lifting platforms 3122 that are matched with the guide surface 3121 of the feeding trough 312 and are constructed in a strip shape are sunken and arranged below the feeding trough 312, and the top surface of the lifting platform 3122 is a lifting surface 3123, and the lifting surface 3123 is parallel to the guide surface 3121 of the feeding trough 312. A plurality of lifting platforms 3122 are parallel to the contact surface of the feeding trough 312 and are arranged adjacent to each other in sequence, and one of the lifting platforms 3122 is adjacent to the contact surface. Each lifting platform 3122 lifts its lifting surface 3123 from the starting height to the ending height. The starting height of the lifting surface 3123 farthest from the contact surface is flush with the guide surface 3121 of the feed trough 312, and the cleaver box 101 accommodated in the feed trough 312 slides to above the lifting surface 3123 of the lifting platform 3122 far away from the contact surface. This lifting surface 3123 drives the cleaver box 101 to rise to its final height. At this time, this lifting surface 3123 is flush with the lifting surface 3123 of the adjacent lifting platform 3122 located at the starting height. The cleaver box 101 slides to the lifting surface 3123 of the adjacent lifting platform 3122 and is lifted again. The final height of the lower end of the lifting surface 3123 adjacent to the contact surface is flush with the top of the contact surface, so that the cleaver box 101 slides from above the contact surface away from the feed trough 312.

[0050] The feed conveyor belt 311 is horizontally arranged on the side of the contact surface of the feed trough 312 and parallel to the contact surface. After leaving the feed trough 312 in sequence, multiple cleaver boxes 101 enter the feed conveyor belt 311. A baffle 3111 is arranged on the side of the feed conveyor belt 311 away from the feed trough 312 to prevent the cleaver boxes 101 from leaving the feed conveyor belt 311. The width of the feed conveyor belt 311 is slightly larger than the outer diameter of the cleaver box 101 and smaller than twice the outer diameter of the cleaver box 101, ensuring that multiple cleaver boxes 101 are arranged in sequence on the feed conveyor belt 311 to prevent the cleaver boxes 101 from being arranged in parallel.

[0051] The height limiting plate 313 is arranged in the middle of the feed conveyor belt 311, parallel to the feed conveyor belt 311 and connected above the baffle 3111. The distance between the height limiting plate 313 and the feed conveyor belt 311 is slightly larger than the outer diameter of the cleaving knife box 101 and smaller than twice the outer diameter of the cleaving knife box 101, thereby preventing multiple cleaving knife boxes 101 from being stacked vertically.

[0052] A return chute 314 is provided on the side of the height limiting plate 313, and the two ends of the return chute 314 are respectively connected to the inside of the feeding trough 312 and the opening of the trough structure surrounded by the feeding conveyor belt 311, the baffle 3111 and the height limiting plate 313. When a plurality of chopping knife boxes 101 are vertically stacked and reach the height limiting plate 313, the height limiting plate 313 blocks the upper chopping knife box 101, so that the chopping knife box 101 is transferred to the rear of the lower chopping knife box 101 so as to pass under the height limiting plate 313, or the upper chopping knife box 101 enters the return chute 314. The return chute 314 is arranged obliquely, and the chopping knife box 101 entering the return chute 314 returns to the inside of the feeding trough 312 under the action of gravity to be re-fed.

[0053] The first slide plate 315 is disposed at one end of the feeding conveyor belt 311 away from the feeding trough 312 and is inclined. The chopping knife box 101 on the feeding conveyor belt 311 slides from the first slide plate 315 to the direction-changing assembly 33 .

[0054] See also Figure 3 and Figure 4 The direction-changing assembly 33 includes a roller frame 331, a first roller 332, a second roller 333 and a roller motor 334. The roller frame 331 is rotatably connected to the first roller 332 and the second roller 333, and is fixedly connected to the roller motor 334. The first roller 332 and the second roller 333 are arranged flush and parallel to the feed conveyor belt 311, and rotate along their central axis driven by the roller motor 334 and a group of synchronous wheels. The first roller 332 and the second roller 333 are adjacent to each other, and the chopping knife box 101 slides off the first slide plate 315 and arrives between the first roller 332 and the second roller 333, and is supported by the first roller 332 and the second roller 333, and rolls with the first roller 332 and the second roller 333. The roller frame 331 as a whole is controllably rotated by the rotating cylinder, and the rotation angle is 180 degrees, so that the cover body 102 of each chopping knife box 101 is oriented toward the direction close to the feeding trough 312. At this time, the setting direction of the chopping knife box 101 is the target direction.

[0055] The visual recognition component 32 is used to identify the direction of the splitting knife box 101 supported between the first roller 332 and the second roller 333, so as to assist the direction-changing component 33 in adjusting the setting direction of the splitting knife box 101. When the direction of the cover 102 of the splitting knife box 101 is different from the target direction, the roller frame 331 rotates as a whole to drive the splitting knife box 101 to rotate. The first roller 332 and the second roller 333 rotate to drive the splitting knife box 101 to roll, so that the label information of the splitting knife box 101 rotates to the sensing range of the visual recognition component 32. At this time, the visual recognition component 32 is also used to identify the label information set on the side wall of the splitting knife box 101, so as to record the storage information of each splitting knife.

[0056] The pushing assembly includes a pushing motor 341 and a pushing plate 342 driven by the pushing motor 341, and the moving direction of the pushing plate 342 is parallel to the direction of the first rotating roller 332. After the setting direction of the cleaver box 101 is adjusted to the target direction, the pushing plate 342 pushes the cover 102 of the cleaver box 101, so that the cleaver box 101 moves toward the rotating gripper 35.

[0057] The rotating gripper 35 is an existing four-claw gripper, which grabs the cleaver box 101 arranged along the target direction, and grabs the end of the cleaver box 101 away from the cover 102. The end of the rotating gripper 35 away from the direction-changing assembly 33 is rotatably connected to the support frame, and is driven by the gripper motor 351 and another set of synchronous wheels to rotate 90 degrees, so that the cleaver box 101 grabbed by the rotating gripper 35 is vertically arranged with the cover 102 facing upward, and the position of the cleaver box 101 is the first position.

[0058] See also Figure 2 The transfer mechanism 4 includes a first manipulator 41, a plurality of transfer assemblies 42 and a second manipulator 43. The transfer assembly 42 includes a transfer track 422 arranged horizontally and perpendicular to the feed conveyor belt 311, a transfer seat 421 slidably connected to the transfer track 422, and a transfer motor driving the transfer seat 421 to reciprocate along the transfer track 422. The transfer seat 421 is used to carry the splitting knife box 101, and the splitting knife box 101 is vertically arranged on the transfer seat 421 with the cover body 102 facing upward. The splitting knife box 101 carried on the transfer seat 421 reciprocates between the second position and the third position driven by the transfer motor. When the splitting knife box 101 is put into storage, the first manipulator 41 transfers the splitting knife box 101 located at the first position to the second position, and the second manipulator 43 transfers the splitting knife box 101 located at the third position to any storage bin 231 in the silo 2. When the splitting knife box 101 is out of the warehouse, the second manipulator 43 transfers the splitting knife box 101 located at any storage bin 231 in the silo 2 to the third position, and the first manipulator 41 transfers the splitting knife box 101 located at the second position to the discharge port 13 provided on the inner wall of the shell 1, and the discharge port 13 is connected to the outside of the shell 1. When the visual recognition component 32 does not recognize the label information of the splitting knife box 101 located at the change-direction component 33, the first manipulator 41 directly transfers the splitting knife box 101 located at the first position to the NG port 12 provided on the inner wall of the shell 1, and the NG port 12 is connected to the outside of the shell 1. In the present embodiment, three groups of transfer components 42 are provided, of which two groups of transfer components 42 can be used for the storage and out of the splitting knife box 101 at the same time, and the other group of transfer components 42 is dedicated to the return of scrapped splitting knives. The relevant structure and specific process of the return of scrapped splitting knives are shown below.

[0059] See also Figures 1 to 3In this embodiment, a material return mechanism 5 is also included, and the material return mechanism 5 includes a material return baffle plate 51, a material return channel 52, a material return sensor 53, and a second slide plate 54. The material return channel 52 is configured as a long strip groove structure parallel to the first rotating roller 332, and can only accommodate the chopping knife box 101, which is arranged in sequence parallel to the material return channel 52, and is formed by a plate-like structure surrounding the end and both sides of the bottom material return conveyor away from the redirection assembly 33. The material return port 14 on the housing 1 is a through hole, corresponding to the end of the material return channel 52 away from the redirection assembly 33, and the chopping knife box 101 to be returned sequentially enters the housing 1 from the material return port 14 and is transferred to the second slide plate 54 through the material return conveyor. The second slide plate 54 is arranged opposite to the first slide plate 315. The splitting knife box 101 leaving the material return conveyor belt slides to between the first rotating roller 332 and the second rotating roller 333 through the second slide plate 54, and is transferred to the third position in the same steps as the storage. The second manipulator 43 transfers the scrapped splitting knife located at the third position to the material return box 55 arranged adjacent to the silo 2. The material return baffle plate 51 is arranged at the end of the material return channel 52. Driven by the cylinder, it can controllably cover or stay away from the opening at the end of the material return channel 52, ensuring that one splitting knife box 101 enters the material return channel 52 each time, preventing the splitting knife boxes 101 in the material return channel 52 from piling up. The material return sensor 53 adopts a photoelectric sensor and is arranged in the middle of the material return channel 52. When the material return sensor 53 senses that the scrapped splitting knife of the returned material passes, the feeding assembly 31 stops running to prevent the normal splitting knife box 101 of the incoming material from being confused with the scrapped splitting knife of the returned material.

[0060] This embodiment also includes a barcode scanner 151, which is placed in a receiving groove formed on the outer wall of the housing 1. When returning materials, the barcode scanner 151 is used to identify the label information of the scrapped splitting knife, and then the scrapped splitting knife is put into the return port 14, so as to further prevent the scrapped splitting knife in the silo 2 from being confused with the normal splitting knife box 101.

[0061] This embodiment also includes a display 16 and a keyboard box 17 arranged on the outer wall of the housing 1. The display 16 is used to display the inventory and in and out status of the splitting knife box 101 in real time, and the keyboard box 17 is used to accommodate a keyboard for convenient information processing. The bottom of the housing 1 is provided with adjustable support legs and universal wheels that are fastened to the housing 1 to facilitate the fixation and movement of the splitting knife dispenser.
